Then, taking a handful as water offering for the deity residing in the solar orb, / he should throw it upward thrice with the gāyatrī. / Immediately after that he should recite the Goddess Gāyatrī according to his ability; / having sipped water for the purpose of water gratification and controlled his breath, the practitioner, / having meditated and cast a handful of water, should gratify the chosen deity— / because of the statement of the Yāmala.
